Answer & Explanation:
work done = force x displacement
work done = (73 x 9.81) x 37 (use 10 instead of 9.81 in o level)
work done = 26496.81 J (27010 J when 10 is used instead of 9.81)
USE THE FORMULA;
Power = work done / time
Power = 26496.81 / 8.9
Power = 2977.2 W (3034.8 W when 10 is used instead of 9.81)
FINAL ANSWER = 2977.2 W (3034.8 W when 10 is used instead of 9.81)
